"We were part of something that was really exciting," Tisdale says of playing their roles in the Disney Channel Original Movie. "Doing a franchise, you become a family with everybody in that cast. It's hard to explain because it's a bond between all of us. Nobody knew that it was going to be super successful. It's not one of those movies that are made after a book and are super successful. For us, it kind of came out of nowhere. We were like, 'Whoa ― what just happened?'"
